JOSEPH \VADLEIGH, OF'MILKS GROVE, ILLINOIS.

HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 276,649, dated May 1,1883. Application filed February 13, 1883. (No model.)

To all whom it may concern I Be it known that I, JOSEPH WADLEIGH, of

Milks Grove, in the county of Iroquois and had to the accompanyingdrawings, illustrating the invention, in which- Figure l is a plan ortop view of a pressingbox and a power embodying my invention; Fig. 2, aside elevation thereof, with the side of the press removed, more clearlyto show the internal parts. Fig. 3 is a vertical section of thepower-wheel. Fig. 4 shows the chain and its pitman attachment removedfrom the pitman and power-wheel.

The object of the present invention is to provide a power-press which issuitable to press hay, cotton, straw, brick, and other material, whichshall be simple, cheap, durable, and officient, and adapted tohorse-power.

The nature of the invention consists of apower-wheel whose periphery isgrooved to carry a chain which is attachedthereto and to a pitman, sothat the pitman will be operated when the power-wheel is turned ineither direction and give to the plunger a movement one-fourth (or less)greater than the diameter of the power-wheel, whereby the pit-man is notthrown so much obliquely to the press-box as when the pitman isjournaled to the wheel by a wrist-pin; and, further, in a tenonattachment to the chain, which is fitted in a mortise in the wheel endof the pitman, so as to be re moved for the convenience of removing thechain for repairs, as the whole is hereinafter fully described andshown.

A B represent the frame of the press-box, and E represents the box. 0 Drepresent the frame which supports the powerwheel J, attached to theframe A B in a substantial manner. This frame, however, may have anyform which will hold the Working parts relatively in .position with thepress-box.

J represents the power-wheel, which is, by means ofa pivot-shaft, K,hung to the frame D, an iron box, M, being employed for that purpose, asshown at Fig. 2. The height of this wheel corresponds to the height of'the pitman G, which is jointed to the middle part of the plunger F ofthe press-box E, as shown at H. The end of the pitman opposite to thepower-wheel is strengthened with a metal plate, I, preferably of steel,and through this plate and into the end of the pitman G is formedamortise, R, to receive the chain attachment V, asshown at the enlargedFig. 4, the top portion of the end of the pitman being broken away at Tto give a plan view of the mortise. The end of the tenon or chainattachment V is provided with an eye, e, to which the link of the chainc is secured in the ordinary manner. This chain may be formed withsquare links, as shown, or oblonglinks; but in either event theperiphery of the wheel J' should be formed,

that the chain may have a smooth and properly-seated bearing, to preventbreakage and unnecessary wear. The chain c, to givea movement to theplunger F a one-fourth greater than the diameter of the wheel J, shouldhe attached to the wheel at a point, m, Fig. 1, and the pitman should beabout two and one-half times as long as the diameter of the wheel. Apitman of less length will answer the purpose, when used with the chainand wheel, to give a. sudden return to the plunger F by the elasticityof the material in the box to be pressed, but will not allow the plungerto pass so faras is sometimes required to admitot' a speedy tilling ofthe press with material. A material advantage of this construction isthat the chain c has only to stand the strain during the time when thelesser pressure is required. When the greater pressure is required, thewheel end of the pitman is brought onto the periphery of the wheel, asshown at Fig. 1, at which point the chain is not subjected to anystrain. The wheel J and pitman Gare shown in position as when theplunger F has the greatest throw into the box E. The dotted lines L 6 cmJ represent the pitman, chain, eye, chain-wheel, and plunger in positionat 9 ter the pitman has passed the point of greatest pressure, and hasbeen made to reboundby the elastic material in the box. a a (dottedlines) show the reverse position of the sweep b where the pitman isthrown to the opposite side of the press-frame. By this means a verysimple, convenient horse-powerpress is provided,

of sufficient strength to press both cotton and hay, also like material;or it may be used to press material less elastic.

It is well to state, with reference to durability, that the periphery ofthe wheel J at f f may be handed with steel, so as to attain strength.Where non-elastic material is pressed the plunger can he suddenlyreturned by a weight or a spring.

I claim as new- '1. In hay-presses and presses for compacting likematerial, the power wheel J, constructed and hung substantially as shownand described, in combination -with the chain c, pitman G, and plungerF, for giving a double I5 rebound movement to the plunger, as and forthe purpose specified.

2. The pitman G of a hay-press, combined with the chain attachment V,tenoned into the pitman, as specified, the wheel J, chain 0, and 20plunger F, as and for the purpose specified.
